Researchers have developed eco-friendly wastewater treatment process that uses common agricultural byproduct to effectively remove pollutants and environmental hormones known as endocrine disruptors.
About this research
In this process, researchers had used rice hulls, discarded during rice harvesting to create eco-friendly and economical, biochar. The surface of biochar was then coated with nano-sized manganese dioxide to create a nanocomposite. The high efficiency and low cost of biochar-nanocomposite catalyst are based on combination of advantages of biochar and manganese dioxide.
About endocrine disruptors
They are also known as environmental hormones. They are chemical compounds that resemble endocrine hormones. They may be either of natural origin (such as phytoestrogens) or of man-made synthetic origin. The sewage wastewater produced at any industrial worksite often contain large quantities of pollutants and such environmental hormones. They have significant negative effect on environment and human body as they do not break down easily. These compounds can also disrupt hormonal activity.
